I've had the chance to have had a teacher who exposed us to the design of robust RST controllers and optimal control (Pontryagin, Lyapunov, Bellman, Hamilton, Jacobi), Evans' work. Getting into an ML shop and looking at what my colleagues who do DL were doing made me think: hmmm, this backpropagation-thingy looks really familiar.

There was, and still is, a comparatively scarcity of documentation on these as most of the content online only tackles PID when it comes to "control systems".

Fascinating stuff.

Soo, if I wanted to look deeper in the maths for these RST controllers, where should I be looking? As I've been confessing in another comment in this thread, I am quite stumped how to proceed to understand more complex controllers. This is all my fault, because of my weak grasp of advanced mathematics.

The best book I know of is pretty old by this point, but it's very readable! Modern Control Systems by Dorf & Bishop. Probably pretty expensive by now, too!

There's also the Control Systems Design Guide, but that's more of a cookbook-style. Dorf and Bishop is a theory book, but a good one.
